. To all, whom it may concern:

Be it knownthat I, THOMAS Dawson, a citizen of the United States of America, and resident of Beverly, in the county of Essex and State of hfaSSlCl1L1StlTS,' l1iU 'Q invented certain new and useful Improvements in Seasoning-Machines, of which the following is a full, clear, and exact description.

This invention relates to machines for treating hides or skins in theprocess of applying seasoning or filling liquor to the surface of the skin. whereby it is rubbed in and at the same time the skin is manipulated and stretched to be thoroughly subjected tothe liquor. I

One of the ob'ectg of the invention is to provide an arrangement of rolls whereby the hide will be caused to be fed between a pair of c'otiper'at-ing rolls, and atliird roll can be brought to engage one faceio f the hide by pressure regulated desired.

A further object isto provide means for feeding the seasoning liquid from a suit- I --able trough or receptacle onto such rolls andto cause the liquor to be fed by the operation ofbringing the said thirdu'oll into engagement with the hide.

'A further object is to provide means op erated bythe said movement of thethird roll whereby the liquor in a suitable recep tacle will be properly agitated.

Another object is to provide one. of the feeding rollswith a surface of soft rubber and to also provide the third roll-which is brought toengage the hideby variable pres: sure with a number of stripsiof fabric .ar-' ranged in the-form of a scroll to cause the hide to be properly stretched. v

' A further objectis to provide in connec tion with such third rolls. one of whichis in the nature of acomparatively large drum, an additional pair of rolls for the subsequent treatment of the hide, with means for bringingsaid rolls into the/proper degree of contactor pressure on the hide; and one; of

which latter rolls can beshifted to be brought into engagement with, the drum in advance of its position of engagement with the other two. rolls whereby the drum and such roll can be utilized for the second treatment-oi": the hide. r

In the accompanying drawings showing I one embodiment of my invention Figui-e 1 IS an end elevation; Fig. 215' an elevation ofthe opposite end; Fig. 3rshows'enlarged a vertical scction;.'Fig. 4'is a detail view showing the scrollroll and-the drum with the means for giving them rotation and also endwise movement to the scroll roll; Big. 0 is a side elevatlon pf the machine.

In the drawings, the machine is shown as provided with a suitable frame denoted QGllof the roll 8 in position to feed the hide onto the top of the roll. -A short distance beyond,' at the upper part of the roll or drum 8 is arranged a feed roll .17 carried by ashaftilb rotatable in suitable hearings in thefraine: A sprocket 19 on theshaft 18 is connected with a sprocket 20 .011 the shaft 12 by a sprocket chain 21, as best shown in Fig. 2; and by this means the drum 8 and roll-17 are'rotated in opposite directions,

which will cause their adjacentportionsto move in the same direction to advance the hide when presentedfhetween their surfaces.

Tlie'bearings 22' for the shaft 18 are slid- .able in a slot 23in the frame on each side and moved upward by a springZ-l against the adjusting bo'lt 25,-Jby which means the positioning of the roll 17 relative to the drum can be nicely regulated. The roll 17 is preferably coated with soft rubber on its periphery: and this roll has the seasoning liquor fed onto it, and carries it around to engage the hide as it'fiasses between this roll and-the drum. p

The trough 26 isshown as of cylindrici'il form and supported by journals 28, 28 at the extremities thereof to be'roclied on its axis. -Alo,ng one side of the trough 26 are a series of openings 29 in horizontal alinement, and upon the trough being filled up to these openings, a slight swing'of the trough to lowerthe openings will cause the liquor therein to be precipitated upon the roll 17 above which the trough is mounted. For feeding the trough .26, a receptacle 30 is arranged-011 an extension 31 of the frame, and.

a plug 32 therein serves to permit the liqnor to flow out from the receptacle and fall 1 roll 50 having its shaft 51 mounted in into an opening 33 in the top of the trough 26; the plug 32 serves to regulate the flow of the liquor. as it may be needed.

Di *ectly above the drum 8 is arranged a scroll roll 34 having its shaft 35 carrying gear 36 which meshes with a gear 37 fast on the shaft 18 of the feed roll 17 by which means the scroll roll is rotated. The shaft 35 of the scroll roll is mounted in bearings in a pair of levers 3S and 39 pivoted on the bearing blocks 22 of the feed roll 17, and by swinging these levers the scroll roll can be moved to and from the drum 9, yet retain its relative position to the roll 17, preferably in contact therewith At the base of the niachineis a treadle 40 connected by rods 41 and 42 with the levers 38 and 39 respectively, and a spring 43 servesto normally retain the treadle elevated and also the levers to hold the scroll roll above and free'from the drum 8.

. After the hide has been placed on the table and passed over the drum 8 to be engaged between the roll 1'7'and the drum, the treadle is depressed, which will bring the scroll roll down onto the hide by pressure varying according to the force exerted. on the treadle. The scroll roll 34 is shown as provided' on its face with spaced strips of felt or other fabric 44 extending in opposite spiral directions from'the middle portion for the purpose of spreading out the hide and distributing the liquor over its surface. It will be noticed that the scroll roll 34 is driven directly from the shaft of-the feed roll 17 by gears, and hence it will be rotated in the same direction as the drum, but the adjacent surfaces will move in the opposite directions, which will facilitate the spreading out of the hide and the distributionofthe liqugr over its surface.

' The swinging trough 26 is provided at its ends with arms 45 which are connected by links 46 with the levers 38 and 39, so that when the treadle is depressed to swing the levers and cause the scroll roll to engage the hide, the trough will be-rocked and spill some of its liquor through the line of openings onto the rubber feed roll 17; and when the levers return tlTe*tro hwvill be swung back and no liquor will be fe unt'rf another hide is presented to the rolls. Means are further provided for agitating the liquor in the trough 30; a weight or bar 47 is connected at its ends with cables 48, 49, passing over guide pulleys 5, 1, in the ceiling or roof, and secured to the levers 38 and 39 respectively; by which means the swlnging of the levers will cause the weight to move up and down in the receptacle and keep the seasoning liquor properly mixed.

After the hide haslbeen subjected to the treatment by the three rolls, it may be given additional treatment by means of another bearing blocks 52- adjustable on-the frame by means of a hand wheel 53 and screw 54, the latter engaging a nut 55 on the bearing blocks. This roll 50 may be thereby shifted over into proximity to the drum 8, and the hide can be treated between these two members, the operator receiving the hide after it passes beyond the rolls 17 and drum 8 and presenting it between the drum and roll 50. Or, if desired, the hide may be passed between the roll 50 and a plain cylindrical brush roll 56 mounted on a pair of arms 57 and 5S suitably pivoted on-the frame, which are connectedwith a treadle 59 by links 60, 61; by which means thebrush roll 56 can be caused to press the hide against the roll 50 with the desired amount of pressure.

The scroll roll 34 during its rotation is also given an endwise movement, this shaft 35 being slidable in the levers 38 and 39, and a coil spring 60 between one end of the roll and the lever 39 serving to press a cam ring 61 on'the other end of the roll against a roller 62, on the lever 38; the gear 36 being provided with a wide face so that the gear 37 will not be shifted out of engagement therewith during its endwise movement ,of the roll. This will further facilit'ate the distribution of the liquor over the surface of the hide and serve to properly stretch the same and to work the liquor into its surface. I

A suitable trough 65 may be provided below the drum 8 and also below the roll 50 to receive the surplus liquor which may drain ofl from the rolls or fronithe hides being treated. I
